Installing Google's Go in Ubuntu 9.10

[eznet]

Google Go
Go is Google's newest offering to the development community. According to the project's page, Go is an expressive, concurrent, garbage collected programming language that is simple, fast, safe, concurrent, fun and (best of all) open source. Touted as a cross between C/C++ and Python, Go seems to be generating a lot of buzz and hoards of seemingly early adopters despite having surfaced only earlier today (11.10.2009) . Of course this is somewhat expected - what has Google ever released that didn't generate it's share of hype/buzz/excitement associated with it?

I bit. I am guessing since you are reading this, you did too.

Getting Ready to Go

The following instructions detail the steps that I used to setup Go on my x64 Ubuntu 9.10 (Karmic Koala) box.

Standard disclaimer: Your mileage may vary. For me everything was pretty much straight forward when following the maintainer's provided setup instructions (http://golang.org/doc/install.html). The only hiccup I encountered during setup was an error with a test during make - Error 2 in [net.test]. A quick bounce over to #go-nuts resolved that - friendly go-nut knowledge base, iant, advised me that there was an issue with this test on some machines in the release version and that I should pull an update. Update pulled, problem fixed.

For simplicity sake, I am working from the gnome-terminal. Access bash as you see fit. When you see '$', it denotes a command to enter in the CLI (Command Line Interface). When you see '>', it denotes and output line.

Installing Required Tools

Install GCC and Mercurial:

 $sudo apt-get install mercurial bison gcc libc6-dev

Setting Up Your Environment

1) Make 'bin' directory for go - You may have one - this will create it for you if you don't:

$mkdir ~/bin

2) Setting up environmental variables:

Edit your Bash environment variables to include the Go required variables as well as making sure your bin folder is in the $PATH

$cp ~/.bashrc ~/.bashrc.bu
$gedit ~/.bashrc

Add following to your .bashrc - note: If using 386, set "GOARCH=386" (worked great on my EeePC):

#Google Go Vars
export GOROOT=~/go
export GOOS=linux
export GOARCH=amd64
PATH=${PATH}:$HOME/bin

Reload .bashrc

$source .bashrc

Note: You can close your terminal session and restart terminal instead. Up to you.

Check out Go ( to your Go root using Mercurial)

$hg clone -r release https://go.googlecode.com/hg/ $GOROOT

Note: I had to pull an update due to errors during make (details below with build instructions):

$cd $GOROOT
$hg pull -u

Building Go

$cd $GOROOT/src
$./all.bash

If successful, results should be:

>--- cd ../test
>0 known bugs; 0 unexpected bugs

Note on make errors: Before pulling an update on the repository, make resulted in:

>make[1]: Leaving directory `/home/eznet/go/src/pkg/net'
>make: *** [net.test] Error 2

Updating via the 'hg pull -u' command above resolved this issue and allowed make to complete as desired.

GO play with Go

Edit:"Installing Required Tools" was modified to skip Python's Setup Tools as mbudde pointed out that mercurial is available from the Ubuntu repositories.

I am getting some errors on the installation of mercurial:

Same error on easy_install mercurial.

When I install the mercurial in synaptic Go's .bash.all fails with:

gcc -m32 -O2 -fPIC -o linux_386.o -c linux_386.c
In file included from /usr/include/features.h:378,

make: *** [linux_386.o] Error 1

(Brand new 9.10 on i386)

[BarryNorton]

Aha, first do a 'sudo apt-get install python-dev' then the mercurial install should work.

Then do a 'sudo apt-get install libc6-dev-i386' and the Go build should succeed

[mbudde]

The section "Installing Required Tools" should just be

$sudo apt-get install mercurial bison gcc libc6-dev

There is no reason to use easy_install to install mercurial.

It appears that you are correct. I think that I must have misspelled Mercurial when looking in Synaptic initially... Doh!

Thanks.

See http://digitalpbk.com/2009/11/instal...o-linux-ubuntu to get a bash script to do it all in one step for 386.

I'm having trouble installing go on my laptop:

%%%% making libcgo %%%%

gcc -m32 -O2 -fPIC -o linux_386.o -c linux_386.c
as -o 386.o 386.s
gcc -m32 -O2 -fPIC -o util.o -c util.c

The environment is identical to my desktop machine where it all went smoothly. Any ideas?

I have followed what you have mentioned.
I am getting the following errors.

mike@ubuntu:~$ cd $GOROOT/src
mike@ubuntu:~/hg/src$ ./all.bash
